High hump comes up as high as the seat bottom in front of the seat.

Re: how to identify high hump vs low hump??
I think mine came factory low hump, but it has a shifter on the floor. The hump looks hastily cut. If I were to replace the entire floor (yes, it needs it) should I go with a high hump? I plan on swapping a T56 or similar into it behind a big block later on.

Re: how to identify high hump vs low hump??
Only low hump floors are made.You can cut and install a high hump,though.

Two wheel drive floor pan vs four wheel drive floor pan? Are they the same?

Re: how to identify high hump vs low hump??
The pans are the same and interchangeable.Only the hump itself is different.As 68350 said,all 4wds had high-hump and only big block or 4spd 2wds did.But,the impression is there for the bolting surface of the high hump.GM offered replacement cabs for a while,but only non-air low-hump.Instructions were included for adapting for both a/c and high-hump.

So this one is unfortunately a low-hump? And I would need a tall hump? |

Re: how to identify high hump vs low hump??
Yes,you can cut the hump out,lay high hump over,drill through mounting hole locations,tack nuts underneath,and you`re done.This is what I`ll be doing on my rust free California cab for my`67 project.I`m using an M22 4spd (which works under a low hump) and I want a high hump for easier access to the shifter assembly.It`s a pain to mess with that stuff all up against the floor and over the transmission.
